This week students started to subtract in math. Their subtraction started with large group visuals to understand how the numbers would become smaller and why this is occurring. They then moved into strategies for subtraction up to 4 digits. Currently, students have not begun exploring questions with regrouping, as we want to ensure the students are comfortable with the process of subtraction before we look into what regrouping looks like.
For example students have been working on:
Getting as much practice with this process will be important for students. The Prodigy website is a good place to get subtraction practice in. Students can also explore this website, which has a ton of online subtraction games:

Next week students will be building into regrouping in subtraction and also working with subtraction word problems.
Students have started a new group project in our Light and Shadow unit. Students are leading a team to design an adjustable flashlight that can both increase the beam width and decrease the beam width at 1 m. This project has multiple stages and will take them to the Winter break. I have attached the section of the Powerpoint they have done so far. Talk to your child about their design and plans for being successful. If your child is becoming frustrated, remind them that all great scientists have to redesign and retest their work.
